Subject: [PATCH 04/13] cgroup: export following two interfaces
Date: Mon, 10 Jan 2022 17:10:37 +0800 [thread overview]
Message-ID: <20220110091046.17010-5-jianchao.wan9@gmail.com> (raw)
In-Reply-To: <20220110091046.17010-1-jianchao.wan9@gmail.com>
From: Wang Jianchao <wangjianchao@kuaishou.com>
This is a preparation for making blk-rq-qos modular, there is no
functional change, but just export interfaces pr_cont_cgroup_path
and cgroup_parse_float.
